I have bought the commercial version. It works like a charme. You can do anything in roles, capacities and menus in front end and backend. Wonderful.
I got a javascript alert, but the plugin works without issues.

How did you managed to put into operation? I do not communicate and writes that: ALERT: JavaScript Error: "TypeError: Can not call method 'removeClass' of undefined". Please read FAQ for more information. I also have WP 3.5

I have the same problem. I have a wordpress 3.5 cz. I plug in version 1.6.8.3 While creating a new category, but I can not assign it to a function like this on video. I only have the Basic version, but that's probably not the problem??
And one more thing, do not work Czech characters. And yet in the older version are going fine.

Right after I built a new category I have access to this category under tab "posts&taxonomies".

The problems with characters I do have also. German umlauts are wrong. I guess it is a problem with a file, that was not converted to utf-8 without BOM. I could not figure out which one yet. But I did no intensive search.
